141. Re: [Amps] variable capacitors (score: 1): Author: Paul Decker <kg7hf@comcast.net>; Date: Tue, 25 Jan 2011 16:54:32 +0000 (UTC); It means one for me, and one for someone else. Does that mean 2 amps into a combiner? What do you use for antenna relays at that power? _______________________________________________ Amps mailing li; /archives//html/Amps/2011-01/msg00267.html (7,659 bytes)
